I have been liking HighlightAll in the past, BUT ,recently it has been interfering with my efforts to copy. When I try to clear the hight light, I can't copy. Is there a fix for this? I just disabled it and am waiting for a solution.

Comprends plus, auparavant (je reviens tester cet addon après quelques années) suffisait d'écrire dans google search les mots clés pour ensuite trouver toutes les occurences dans les articles, textes, etc, sans avoir à faire une seule manip, là c'est devenu une usine à gaz, et impossible de trouver un autre addon qui fasse le taf simplement.

Does exactly what I need, but it is a pain to use it. Highlighting is extremely slow – it takes several seconds. The animation for color selection box is annoyingly long and also currently broken (it disappears).

This add-on made paper reading so easy for me!!

So far so good. I was looking for just the basic feature, but I found the multiple-word custom highlight feature even more useful!

I'd like word selection to activate the standard highlighting even when using custom colours (i.e. I select the word -> it highlights all instances with native colour + it shows the custom colours popup)

Custom highlights can be deactivated through the right-click menu. However I think it would be better to have a blank X button next to the other colours.

Merci au dev pour cette indispensable extension

Excellent Addon. Thank You.
One bug though. When the selected text has open and close brackets (...), the selection goes away, only the highlight remains. Pressing Ctrl-C after that copies no text.
Another problem- It does not work on simple text files. It also does not work on the mozilla addons site.
Thanks.

Edit- After few days of use I found it is full of bugs.

Didnt seem to work at all. Im on windows using firefox 65.0.2 (64-bit). I wanted to see highlighting in the scrollbar but did not.

This is an extremely useful tool, that helps increase my productivity in my day to day work. Will recommend to colleages as well.

Custom mode is quite slow, at least on my use case. So I am sticking with native mode, as it is significantly faster.

If only it was possible to click on the "number of occurrences" pop up to take you to the next occurrence, it would be perfect! :)

Excellent Add-on. Must have.
Very useful improvement — to have a shortcut to un-highlight all. Currently it's only page refresh.
Possible improvement — when multiple colours are set, every new selection gets automatically the next colour.

Very handy. The one thing I didn't like about Firefox's Find feature was that it doesn't show the occurrences on the side scrollbar like Chrome does, which makes it hard to actually find where the matches are. This addon provides that, and in my opinion this feature should be in Firefox itself.

Нужное и удобное дополнение разработали!

Sadly It does not work for a bigger pages.

Doesn't work.
